Pick one — models revealed after.Both summaries are AI-generated. Summary A Devin's testing capability has improved with GPT-6 Astra, enabling it to autonomously verify its own work, which reduces the amount of code engineers need to review, directly accelerating their shipping process. Summary B GPT-6 Astra enables Devin to autonomously test code with higher accuracy, reducing engineers' manual review burden by 20–30%. This lets teams deploy faster with greater confidence in autonomous agent outputs, but requires adapting validation workflows to handle AI-generated test cases at scale. 0 picks
